Memphis Depay: I want to be the GREATEST player in the world

The Holland sensation has become United's first summer signing after joining from PSV Eindhoven in a £25m deal.

He will join-up with United when the transfer window re-opens in July after penning a long-term deal worth £130,000-a-week.

The 21-year-old has wasted no time in setting his sights high and has backed himself to join Lionel Messi and Cristiano Ronaldo as the most formidable footballers in the world.

Depay, who was one of the Dutch's brightest stars at last summer's World Cup in Brazil, said: "I believe I can be one of the best players in the world.

"I have to dream and believe to achieve. It is tattooed on my chest.

"You just have to work every day on your dreams. My dreams started with going to the World Cup and then when I was there I scored two goals - becoming the youngest ever Dutch goalscorer - and I was very happy.

"But when the World Cup was finished I realised that was not it. I had to take more on to the pitch - there was more to do.

"So after the World Cup in pre-season I spoke to my manager and said I have to keep focused.

"Scoring in the World Cup was good but not the end of it. Now I am on fire."

Depay admits Ronaldo is one of his heroes and is determined to emulate the United legend by taking the Premier League by storm.

The winger, who scored 25 goals this season to fire PSV to the Dutch title, added: "I want to improve myself and I believe I can be a big player in the Premier League.

"I am very excited. I was always reading about the Premier League. It has been a big dream and one that came true. But is not the end of the dream, it is just starting.

"I am 21 and I have not reached the level of Cristiano Ronaldo. He is a big hero for me and one day I hope to reach that level.

"He scores so many goals and I want to fight to be one of the best players in the world."

Depay is expected to be the first of several United signings this summer as boss Louis van Gaal goes on another huge spending spree.

Mats Hummels, Nathaniel Clyne, Gareth Bale and Asimir Begovic are also targets and United chief executive Ed Woodward is expected to shed some light on Van Gaal's spending plans today.

United will announce their latest financial results at noon and Woodward will host a conference call with club investors, when the subject of Van Gaal's transfer plans will come up.
